Thank you for the last decade we spent together. It’s been an incredible ride with warmth, friendship, and support. Together we’ve brought validations and verifications to the next level. A…

What do you measure when you measure bias?
Two studies that are among our most used studies at the moment, are about measuring bias or difference between methods or instruments producing quantitative results. This is something which practically…
Back to basics – rethinking Validation Manager
As Validation Manager already contains quite a wide range of features, we have had an opportunity to do some upkeep tasks, sort of cleaning up and renewing things that have…
Three+ tips to reduce repetitive work
Validation Manager saves a lot of your time in data management and analysis, as well as in reporting your validations and verifications. But even if you know that you will…
Quantitative comparisons refined
For some time already we’ve been considering ways to help our users with their quantitative comparison studies. Earlier, we had a study for comparing instruments running same assays, and another…
A few words about confidence
When doing validations and verifications, we statistically estimate different performance characteristics of a method. The values gained by calculations never give exact information about the method under examination. So how…
New winds for Quantitative Accuracy
We’ve recently published Quantitative Accuracy study, the coolest study in the history of Validation Manager. For the first time, we have enabled determining systematic error and random error in a…
What’s with the precision?
When establishing precision of a method, we are interested in the methods ability to produce consistent results. Precision measures the closeness of agreement between measured values obtained by replicate measurements…
4 steps towards smoother validations
In the midst of the hectic laboratory work, validations may sometimes feel like a meaningless burden. It would be so nice to get them quickly out of the way and…
How low can we get?
When validating a new method, one of the key questions to be answered is how low analyte concentrations can be reliably detected. Here’s a short summary about relevant concepts and how…
